The Ergonom Technology
The Ergonom Series of Microscopes
In 1972, Kurt Olbrich investigated why the resolution and depth of field, of existing light microscopes,
is so limited. In 1976, he discovered a unique new way of building microscopes where by using a
different approach to optics and a new mathematical approach, he could build microscopes with a
large "cylinder of sharpness" (depth of field) and a true resolution better than 100nm, while
maintaining full contour sharpness and true colours without the need for staining, oil immersion, etc.
The Ergonom 4000-3 is our top
model and a direct successor of
the Ergonom 500, with the same
high resolution, depth-of-field,
etc, yet is now even easier to
use. It can be separated into 3
major parts for transport, and the
illumination system has been
further improved with the choice
of a separate halogen lamp
system, or an internal special
LED light source. The microscope
is built entirely to our own
specifications in order to guarantee the use of top quality components.
Depth of Field: All Ergonom microscopes feature variable depth of field where the true colours and
contour sharpness remain clearly discernable, even with ever increasing magnifications comparable with that
of mid-range scanning electron microscopes. This makes it possible to vary the depth of field independently of
magnification, which also allows much more detail to be seen (see image on right), live and in real time!
No Staining, No Oil: The unique optical system provides so much contrast that staining is not required.
This allows you to observe the specimens, under a white light source, in their true (living) state, in vivid contrast
and true colours even at the highest magnifications. All objectives remain dry as oil immersion is not required.
Grayfield: An entirely new method in optical microscopy is the Grayfield method, developed by Kurt Olbrich.
This method allows you to see detailed structures that are otherwise not even visible with conventional phase
contrast microscopes. For example, the Grayfield method allows you to observe the in vitro decomposition
processes of blood. During this transitional phase new viruses and structures arise, which tend to decay and
could previously not be made visible due to the lack of suitable microscope techniques.
Phase Contrast: The phase contrast method is used for all thin-layered structures including fibres and
textiles. With conventional methods, focusing is limited by overlapping layers and the structures also have the
same fractal index causing the structures to become blurred. The Ergonom technology removes these
limitations and provides clear and sharp contours.
The Ergonom 4000-3 is the top model offering both incident (
